Date: Week 34
Lesson Duration: 45 minutes
Week & Period: Week 34, Period 6
Topic: Data Handling
Sub-topic: Collection and Representation of Data
Learning Objectives
By the end of the lesson, students should be able to:
• Construct and interpret frequency tables, bar graphs, line graphs, and pie charts
• Collect and record data using tally marks
• Calculate mode, mean, and median from simple data
Previous Knowledge
Students already know how to count and arrange numbers in order.
Instructional Materials
Mathematics textbook for Grade 3, graph papers, rulers, markers
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks: “How many brothers and sisters do you have?” and records responses on the board as tally marks.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Data is information collected about people or things.
Frequency table – shows how often each item occurs.
Bar graph – uses bars to represent data.
Line graph – uses lines to show change over time.
Pie chart – circular chart divided into parts.
Mode – most frequent value.
Median – middle value in ordered data.
Mean (average) – sum of values ÷ number of values.
Example: Favorite fruits data collected in class. Represent in a bar graph and find mode.
Learners’ Activities (Expanded):
Learners collect data on favorite colors in class. They tally results, draw bar graphs, and calculate mode.
Assessment Checks:
Teacher asks:
• What is the mode of the data collected?
• Which graph shows change over time?
Notes (Expanded & Detailed):
Data representation helps us understand information easily. Graphs make data clearer. Mode is the most common, median is the middle, mean is the average.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher revises data, frequency tables, and graphs.
Evaluation Method (Expanded):
Exit slip/quiz: Draw a frequency table showing number of siblings in your row.
Assignment (Expanded):
Draw a bar graph showing the number of students in each row of the class.
Follow-up Activity:
Learners collect data at home (e.g., number of cups used daily) and present.
Differentiation / Inclusive Strategies
Learners who struggle may use guided graph templates. Advanced learners calculate both mean and median.
